Kynu Gene Summary [Rat]
Enables kynureninase activity and pyridoxal phosphate binding activity. Involved in L-tryptophan catabolic process to acetyl-CoA. Predicted to be located in cytosol; mitochondrion; and nucleoplasm. Predicted to be active in cytoplasm. Used to study hypertension. Human ortholog(s) of this gene implicated in hydroxykynureninuria. Orthologous to human KYNU (kynureninase).

Protein Domains
A protein domain is a distinct structural or functional region within a protein that can evolve, function, and exist independently of the rest of the protein chain. These domains in rat Kynu often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
